Import Tips
• Alloy steel must have specified elements (Cr, Mo > threshold); provide chemical analysis certificate (Ladle analysis)
• Wall thickness tolerance is +/-12.5%; document actual measurements to prevent under/over thickness disputes
• Ship in protected bundles with end protectors; customs may inspect for thread damage affecting classification
